SERVICE OR WATER TANK FOR WATER-CLOSETS.

SPECIFICATION forming part ofLetters Patent No. 392,359, dated November6, 1888.

Applicution filed November 25, 1887. Serial No. 256,150. (No model.)

To aZZ whom it may concern.-

Be it known that I, FRANK H. PARADIOE, a subject ofthe Queen of GreatBritain,but a resident of Denver, in the county of Arapahoe and State ofColorado, have invented a new and useful Service or Water Tank forWater-Glosets, of which the following is a specification, referencebeing had to the accompanying drawings, forming part hereof.

. My invention relates to that class of service or water tanks forflushing closets, bowls, 810., in which a siphon is used to effect thedischarge of the flushing-stream; and its objects are to furnish a tankhaving a siphon-discharge easily thrown, when desired, into certain andspeedy operation and with necessary force, of simple construction,durable, and reliable, to which ends it consists in the features moreparticularly hereinafter set forth and claimed.

In the drawings is illustrated a tank embodying my invention, in whichdrawings- Figure 1 is a vertical longitudinal section of such a tank,and Fig. 2 a.top or plan view thereof.

In the figures, the reference-numeral 1 indicates the service or supplytank,from which leads a discharge-pipe, 2, for conveying thewater fromthe tank to the article to be flushed. This disch arge-pipe 2 forms ineffect the longer limb of a siphon, and it extends within the tank as anenlarged extension, 3, whose upper edge is just above the line at whichit is desired to normally maintain the water-level This enlarged end maybe of the shape of a funnel or of an inverted pyramid, the'latter beingthe form herein illustrated, the sides graduallyinclining inwardly untilthe regular diameter or size of discharge- 2 is reached. Surroundingthis enlarged portion 3, and with walls or sides concentric or parallelthereto, is a cap, 4, supported from 3 by arms or lugs 5.- It extendsalmost to the floor of the tank and forms the shorter limb or member ofa siphoncompcsed of it and pipe 2,with enlargement 3. The greatestenlargement of 3 relatively to the normal size of 2 is such that a smalloverflow around the entire upper edge of 3 shall be sufflcient, flowingdown and converging in 2 to fill 2, so as to instantly start thesiphonage, and that with considerable force.

Passing vertically through the tank is a tube, 6, upon which is seated adisplacementfloat, 7. This seating is by means of a tube, 9, passingthrough an axis of the float and carried some little distance beyond itsupper limit. To this extended end of tube 9, or to a cap or bracesecured thereto, is attached a pull cord or chain depending therefromthrough tube 6, so that the displacement-float 7 may readily be pulleddown into the body of the water in the tank, raising the waterlevelsufficiently to instantly start the siphon 2 3 4 into operation.

11 is an ordinary service or supply pipe having a vent or nozzle, 15,for conducting water into the tank, and an ordinary valve, 12,controlled and operated by the lever 13. This lever is attached to thefloat 7 ,or to its tube 9, so as to move therewith, and the parts are soadjusted that the float 7 shall cause the closure of the valve when thewater is at the desired normal level, the float causing the opening ofsuch valve whenever it is pulled down to cause the displacement of waterto start the siphon into operation.

This construction forms a very elfective, reliable, andspeedily-operating tank, the size of the float and the surface of thewater being such relatively to each other that a very little more thannormal submergence of the float starts the siphonage. A direct pull onthe float is secured, avoiding any extra lever for that purpose, and theone float is made to do the double duty of starting the siphonage andcontrolling the inlet-valve.

The peculiar construction of the siphon insures economy and ease ofconstruction and durability, as well as reliability.

Having thus described my invention, what I claim is- 1. The combination,in a flushing-tank, of a siphon having the upper end of its longer limbmade as a funnel or an inverted pyramid whose walls flare outwardlyuniformly from the bottom or near the bottom of the tank to the top ofthe limb,and having its shorter limb with walls parallel or concentricthereto and supported by arms therefrom, a tube extending verticallythrough the tank, a displacement-float attached to a second tube seatedupon the vertical tube,a pull cord or chain dc pending through thevertical tube, an inletvalve,and a rod connecting such valve and thefloat, substantially as set forth.

2. The combination, in a flushing-tank, of a siphon consisting of tube2, with the enlarged end3, whose sides or walls flare uniformly outwardfrom the base or near the base of the tank, a cap, 4, having sides orwalls concentric thereto and supported therefrom by arms or braces 5, atube, 6, extending vertically through the tank, a tube, 9, slidingthereon, a displace ment-fioat, 7, secured upon 9,eord 10, dependingthrough tube 6,and inlet-valve 12 and rod 13, connecting 12 and 7,substantially as set forth.

3. The combination, in a fluslling-tai1l ,ofa siphon having the upperendof its longcrlimb made as a funnel or an inverted pyramid whose Wallsflare outwardly uniformly from the bottom or from near the bottom of thetank to the top of the limb, and having its shorter limb made with sidesor walls concentric or parallel thereto, and supported by arms or bracesattached to both the longer and the shorter limb, a tube extendingvertically through the tank, a displacement-float seated thereon, andmeans for manipulating the float, substantially as set forth.

In testimony whereof I have hereunto affixed my signature, in thepresence of two witnesses, this 3d day of November, A. D. 1887.

FRANK H. PARADIGE.
